Title: Monitoring arrangement for accurately controlled voltage supply - incorporates the monitoring network in the voltage control loop
Inventor: VITTERS HANS-HEINRICH
IPC: G05F1/571
Filed: 1974-01-25
Abstract: A new monitoring arrangement is given for an accurately controlled voltage such as required for the klystron supply in a transmitter. The traditional arrangement, which is described is to have the monitor circuit attached to the supply external to the control loop. If the supply then falls outside given tolerance- typically plus-or-minus 1% - the monitor switches the system off. The monitor must in this case be more accurately constructed than the othr control loop elements. In the proposal presented here, the monitor circuit is fed from the amplified difference signal in the control loop between the controlled voltage and the set point voltage. As a result a considerably less and accurate monitor is required to give the same results. The effects of noise in the loop and of changing the set point are also considered.

Title: Video signal transmission system - uses difference between input signal and predicted signal which is quantised and transmitted
Inventor: BOSTELMANN GERT DIPL ING
IPC: H03M3/04
Filed: 1974-02-06
Abstract: This signal is decoded at the receiving end and reconverted into the original signal. The quantised difference values are so digitally coded by a code converter, that positive differences are transmitted as the corresponding n-digit binary number, and negative differences as an n-digit binary number of the 2n complement of q, where q = 2n-q. Reconversion of the transmitted binary values is done at the receiver by continuous addition of the received difference value to the preceding sum (predicted value) by a modulo n adder. The sender quantiser has a characteristic symmetrical with respect to the value 0.5 x 2n.

Title: Portable self-closing liquid container of plastics sheet - is closed by sheets in contact at mouth
Inventor: CARLISLE RICHARD SHELDON
IPC: B65D47/20
Filed: 1974-05-21
Abstract: A container for liquids or other flowing media is consituted of two sheets of flexible, impermeable material, e.g., polyethylene, joined together by two opposite seams and having a mouth which is closed without the use of a separate stopper or clamp. When filled with liquid but not under pressure, the two sheets move apart from each other to provide the container void and taper towards one another at an angle of less than 90 degrees until they come into contact along a generally curved line; from this point onwards, in the normally filled but closed state, the two sheets lie in close contact with one another for a distance until the mouth of the vessel is reached. To eject liquid from the vessel pressure is applied to its sides; this causes the converging angle of the two sides of less than 90 degrees to be opened out so that the contact line forming the commencement of the sealed mouth is moved progressively forwards until it reaches the mouth and the vessel is thus open to discharge liquid. The container is any vessel for contg. liqs. which are to be discharged in portions are reqd. and where the vessel is to be closed again when desired without the use of a separate stopper, e.g. a portable drinking vessel.

Title: Tufting by inserting pile loops into backing fabric - and after cutting loops pulling them into J-shape pile tufts
Inventor: CARD ROY T
IPC: D05C15/32
Filed: 1974-09-04
Abstract: A tufting device uses a tufting needle to insert loops of pile yarn into a backing web and has a loop former which engages each loop as it is formed and moves into a position in which it can be cut by a cutter to produce a J-shaped pile tuft having a front pile fibre projecting from the surface of the backing web and a back pile fibre which projects from the web surface and which is shorter than the front pile fibre. The J-shaped tuft is then filled through the backing web to accentuate the difference in height between the front and back pile fibres. Normally an attempt is made to eliminate J-shaped tubts which are formed automatically because of themethod of cutting. By controlling the height of the front and back pile fibres of each J-shaped tuft a novel and uniform pile can be produced.

Title: Voltage and frequency converter for AC loads - output comprises succession of positive and negative pulse trains
Inventor: MERINO DE LA FUENTE RAMIRO
IPC: G05F1/10
Filed: 1975-04-11
Abstract: Circuits of this type are normally applied to variable speed a.c. motor drives. In the converter the loads, for example motor windings, are connected across a triac bridge fed from a.c. supply lines. A full wave rectifier gives signal pulses which are then shifted in phase with respect to the supply by a delay circuit. A trigger circuit converts these pulses into rectangular form. Counting and routing circuits then direct the signals to the triggering circuits of the triacs. By selective firing of the triacs to maintain current direction on the load for longer than would normally be possible at mains frequency, a frequency change in the motor supply is achieved.

Patent DE-2524804-A1 (DE)
Inventor: SUZUKI MATSUMI
IPC: G10L15/10
Filed: 1975-06-04
Abstract: Speech recognition in prior art uses one extracted characteristic component (xi) to represent one phoneme (Xi) as spoken by one speaker. This invention provides for recognizing the same phoneme as spoken by different speakers, by deriving a group of such components (xik), each a slight variant of the others, to allow finding one component most similar to both the specific phoneme and specific speaker, the method comprising the steps of: normalizing the sound pressure level of an input speech from an unknown speaker; analyzing the normalized voice in a plurality of channels having different frequencies; setting, with respect to the output Fj of each frequency band thus analyzed, a weight  alpha j of the output Fj so that weight alpha j corresponds to a characteristic of a predetermined phoneme Xi; extracting the characteristic component xi of the phoneme Xi, setting a weight  beta j of output Fj so that, when the extracted characteristic component xi causes a malfunction or error due to another phoneme Xe, a characteristic of phoneme Xe is corresponded to; simultaneously extracting the characteristic component xe of phoneme Xe and, when the difference between the characteristic components thus extracted is greater than a predetermined threshold value  gamma i, applying the difference as a characteristic parameter for the phoneme xi; expanding the characteristic parameter to obtain a characteristic parameter group based on the characteristic parameter, each being slightly different from each other so as to be adapted for individual characteristics of different speakers; subsequently extracting from the characteristic parameter group a characteristic parameter, having maximum similarity to a reference parameter previously memorized, as an adaptive parameter adaptive to the unknown speaker; and, matching a standard pattern derived from the extracted adaptive parameters with an unknown pattern corresponding to the unknown speakers, thereby effecting recognition or analysis of the voice.
Patent DE-2527170-A1 (DE)
Inventor: INOUE SOUICHI
IPC: G04D7/12
Filed: 1975-06-18
Abstract: An apparatus for adjusting the frequency of an oscillating element provided with a hair sp extracts an oscillating signal from the oscillating element which is oscillated by the elastic force of the hair spring. High frequency pulses are counted by a counter during a predetermined period of the oscillation signal. On the other hand, further high frequency pulses are counted by another counter. When the count value of the latter counter coincides with that of the former counter, the input pulses to the latter counter are stopped by the coincidence output. Until the coincidence between the count values of both the counters is established, the hair spring is transported to adjust the length thereof. Thereafter, the unnecessary hair spring is cut away. Since this apparatus detects an appropriate length of the hair spring by electronic circuitry, it is small in size, and the unnecessary length of hair spring is automatically cut away.
